SURFACE PREPARATION SPECIFICATION NO. 3 Power Tool Cleaning

1.1 This specificationcovers the requirementsfor power tool cleaning of steel surfaces.

4.1 Before power tool cleaning, remove visible oil, grease, soluble welding residue, and salts by the methods outlined in SSPC-SP 1.

2. Definition 2.1 Power tool cleaning is a method of preparing steel surfaces by the use of power assisted hand tools.

4.2 After power tool cleaning and prior to painting, reclean the surface if it does not conform to this specification.

2.2 Power tool cleaning removes all loose mill scale, loose rust, loose paint, and other loose detrimental foreign matter. It is not intended that adherent mill scale, rust, and paint be removed by this process. Mill scale, rust, and paint are considered adherent if they cannot be removed by lifting with a dull putty knife.

4.3 After power tool cleaning and prior to painting, remove dirt, dust, or similar contaminants from the surface. Acceptable methods include brushing, blow off with clean, dry air, or vacuum cleaning.

5. Methods of Power Tool Cleaning

2.3 SSPC-VIS 3, I S 0 8501-1:1988 or other visual standards of surface preparation agreed upon by the contracting parties may be used to further define the surface.

5.1 Use rotary or impact power tools to remove stratified rust (rust scale).

3. Reference Standards

5.2 Use rotary or impact power tools to remove all weld slag.

3.1 The standards referenced in this specification are listed in Section 3.4 and form a part of the specification.

5.3 Use power wire brushing, power abrading, power impact or other power rotary tools to remove all loose mill scale, all loose or non-adherent rust, and all loose paint. Do not burnish the surface.

3.2 The latest issue, revision or amendment of the reference standards in effect on the date of invitation to bid shall govern unless otherwise specified.

5.4 Operate power tools in a manner that prevents the Formation of burrs, sharp ridges, and sharp cuts.

3.3 If there is a conflict between the requirements of any of the cited reference standards and the specification, the requirements of the specification shall prevail.

5.5 Regardless of the method used for cleaning, if specified in the procurement documents, feather edges of remaining old paint so that the repainted surface can have a reasonably smooth appearance.

7. Safety 7.1 All safety requirements stated in this specification and its component parts apply in addition to any applicable federal, state, and local rules and requirements. They also shall be in accord with instructions and requirements of insurance underwriters.

8.3 Note that the use of visual standards in conjunction with this specification is required only when they are specified in the procurement documents (project specification) covering the work. It is recommended, however, that the use of visual standards be made mandatory in the procurement documents. SSPC-VIS 3, “Visual Standard for Power- and HandTool Cleaned Steel,” provides color photographs for the various grades of surface preparation as a function of the initial condition of the steel. For more information about visual standards, see SSPC-SP COM, Section 11.
